Vancouver police are not recommending charges in the overdose death of 15-year-old Adriana Falcon, a conclusion her frustrated father blames on investigators dropping the ball.

Rick Falcon was grief-stricken when his daughter was found dead in a West End apartment Sept. 16. That grief turned to anger last week when he got a call from police informing him the case had been closed.

“I really hoped that at the very least we’d be able to get a criminal negligence charge,” Falcon said. “It’s a slap in the face to my daughter and her family.”

The Vancouver Police Department confirmed investigators looked for Adriana’s dealer but Const. Brian Montague said they found no evidence they could use to pursue charges.

“That’s something we can’t do in Canada,” Montague said. “There’s nothing in the Criminal Code where we can hold someone accountable for someone else’s death if they willingly ingest or take drugs and die of an overdose.”

Charges weren’t pursued in the overdose death of actor Cory Monteith last summer for the same reason, but Falcon said his teenage daughter died in a man’s room, and someone should be forced to take responsibility.

“If we can’t make a case for criminal negligence for a 15-year-old girl being found dead in this guy’s room… it’s sickening,” he said.

Montague insisted police have done everything they can to help bring the family closure. Though the case was closed early on and handed over to the BC Coroners Service, investigators re-opened it a month later when new evidence came to light.

“I’m the father of two young daughters myself,” Montague said. “We have to look at this from a police standpoint, ask ourselves if there was a criminal offence committed here, and unfortunately the answer is no.”

Police have not commented on the evidence that convinced them to reopen the case.

Falcon vowed to continue fighting for justice for his daughter, and is planning to start a foundation in her name with his family.

“It’s been very hard. It was five months ago yesterday when we lost her, and it feels like yesterday,” he said.

“We’re sticking together, we’re moving forward.”
